Customer experiences on forums:
Pricing and Value
General thoughts on pricing show competitive rates initially, but customers express concerns about sudden increases and billing system problems:
"Grinnell Mutual offers slightly higher rates than many other comparable insurers. Its liability-only policies average $55 per month, and its full-coverage policies average $114 per month."
"In July my rate went up to $_____ per month and the adjusted difference of $707.13 was automatically taken on July 17th. There was no notification or reasoning for the price change."
Claims Processing
Most customers have mixed experiences with claims, ranging from quick resolutions to prolonged disputes with unresponsive adjusters:
"When I was in my first major car accident in 2008, Grinnell worked with me to help in the quickest way possible. Not having to wait a long time to get a rental was a plus."
"The WORST customer service service ever, so rude, unprofessional, the adjuster never returns your phone call. In 2023 will be a year the claim is still open."
Customer Service
Agent service receives significantly below-average ratings compared to industry standards, with numerous complaints about responsiveness:
"Grinnell Mutual's customer service scores leave something to be desired. The company isn't accredited by the Better Business Bureau, and the reviews on the BBB website, Yelp, and Google range from 1.5 to 2.9 star ratings."

Trust and Reputation
As a mutual company with over a century in business, Grinnell maintains decent financial stability but faces reputation challenges due to customer service issues:
"Grinnell has been in business for more than 100 years. While it's not accredited by the Better Business Bureau, it earned an A rating for AM Best for its financial stability."
Coverage Options
People appreciate the Mile Marker loyalty program and farm-focused options, but note the limited availability in only 12 states as a major drawback:
"Grinnell's Mile Marker Auto Loyalty program offers small at-fault accident forgiveness. You can take advantage of Grinnel Mutual's discounts to pay less in car insurance."
REVIEWS ON FORUMS AREN’T A PERFECT GAUGE
Negative reviews dominate forums but don't represent overall service quality. For a complete picture, check J.D. Power ratings, independent agents, the National Association of Insurance Commissioners (NAIC) and the Insurance Information Institute alongside user reviews.
